I do not think there will be the negativity from Blurt users if you still are active on the other two platforms. The negativity on hive was brought over from steemit. From what i am reading on Blurt's Discord Server the people behind this platform seem sincere in creating a good platform without all the drama...

Now there are Hive people who try and bring their drama to Blurt, but they are the same one's who brought it from steemit. For now I am letting it run and see how this plays out.
